Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed April 16, 1908. Serial No. 427,311.

To all whom it may concern:

Be it known that I, OTTO SELG, a citizen of the United States, residingat New York city, Manhattan, county and State of New York, have inventednew and useful Improvements in Fans, of which the following is aspecification.

This invention relates to a fan provided with novel and effective meansfor distributing the blast over an extensive area.

In the accompanying drawing: Figure 1 is a side elevation, partly insection, of my improved fan; Fig. 2 a detail of part of the outerdeflector; Fig. 3 a similar view of the inner deflector; Fig. 4 a crosssection on line 4-4, Fig. 2; Fig. 5 ,a cross section on line 5-5, Fig.2, and Fig. 6 a cross section on line 66, Fig. 3. a

In the housing 10 of an electric fan turns the shaft 11 of the windvanes 12, as usual..

Centered in front of the housing is an upright rod 13 secured thereto byscrews 14. Rod 13 is embraced by a socket 15 held thereto by aclamp-screw 16. To this socket is secured a cruciform frame 17 extendingthrough an annular outer deflector 18. This deflector .is made in theshape of a belled ring which is slitted transversely at intervals fromits front to within a suitable distance from its back. In this way thereare formed, integral with the ring, a series of curved blades 19, 20,which are bent outwardly, so as to diverge towards their free edge. Ofthese, blades 19, which alternate with blades 20, are made straight incross section, (Fig. 4), while blades 20 are made V-shaped in crosssection at their forward ends, (Fig. 5). Thus, while blades 19 willdiffuse the air in wide strata, blades 20 will deflect it inconcentrated radial currents that alternate with such strata. In thisway a wide spreading of the air, and an eflective cooling action will beobtained.

Within the first or outer deflector 18 is contained a second or innerdeflector. This inner deflector is composed of a. ring 21 to which aseries of flaring blades 23 are secured. The inner deflector is sospaced from outer deflector 18, that an annular air passage is formedbetween them. Ring 21 is held concentrically to deflector 18 by means ofa series of rods 22 secured to frame 17.

As shown, blades 23 are slotted as at 24 for the reception of clampscrews 25 engaging ring 21. By setting the blades 23, either backward orforward, the volume and direction of the blasts passing through theinner deflector, and between such inner deflector and the outerdeflector, may be readily varied.

I claim:

. 1. A fan provided with an annular slitted deflector having a, seriesof blades that are V- shaped in cross section, substantially asspecified.

2. A. fan provided with an annular slitted deflector having a firstseries of blades that are straight in cross section, and a second seriesof blades that are V-shaped in cross section, substantially asspecified.

3. A fan provided with an outer ring having deflecting blades,. an innerconcentric ring, and deflecting blades adjustably mounted on the innerring, substantially as specified.

4. A fan provided with a slitted annular deflector having a series ofintegral diverging blades. a ring concentric to said deflector,

and blades adjustably secured to said ring,-

substantially as specified.
